Hassleblads have an internal shutter behind the reflex mirror that folds
open before the leaf shutter is opened.
My understanding of the sequence:
- leaf shutter closes,
- lens auto-diaphram closes,
- viewing mirror swings up,
- in-body shutter opens,
- leaf shutter exposes film,
- process operates in reverse to resume viewing.
I'd be surprised if someone can rig up something to use an OM body/leaf
shutter in some sort of pseudo-automatic method. But I've been surprised
before?

Hmm, this doesn't really sound right. I would think you should be able to
rig something up (possibly with help of a motor drive) that would cock the
leaf shutter, open the oly shutter at 1/4 or so (for tolerances) fire the
leaf shutter once for exposure and again locked open. (I am assuming, since
hasselblad can be reflex, that they know about leaving a shutter open for
viewfinding -- or am I a complete loon?)
